At this time, CBP has allowed access to a web-based portal to accept ISF filings. Use of the portal is limited in scope; eligible importers may have no more than 12 filings per year. The ISF portal can be accessed through the ACE Secure Data Portal.

• Importers must apply for an ACE portal account before being granted access to the ISF portal. The application can be found here: https://www.cbp.gov/trade/automated/getting-started/portal-applying

• Importers must register their importer ID numbers with CBP (e.g., IRS number or SSN). Registration can be done in person at a local port of entry, or by a licensed customs broker via the use of CBP Form 5106.
